OILING DEVICE.

SPECIFICATION forming part of. Letters Patent No. 708,448, datedSeptember 2, 1902.

Application filed November 23, 1901. Serial No. 83,382. (No model.)

To all whom, it may concern:

Be it known that I, ALBERT OBEN WYMAN, a citizen of the United States,residing at Turners Falls, in the county of Franklin and State ofMassachusetts, haveinvented certain new and useful Improvements inOiling Devices, of which the followingis a full and completespecification, such as will enable those skilled in the art to which itappertains to make and use the same.

The object of this invention is to provide an improved oiling deviceparticularly designed for use in oiling loose pulleys or other pulleysor devices mounted on a shaft or axle; and with this and other objectsin view the invention consists in an oilin g device constructed ashereinafter described and claimed.

In the drawings forming part of this specification, in which theseparate parts of my improvement are designated by the same referencecharacters in each of the views, Figure 1 is a central longitudinalsection of my improved oiling device, the section being taken on theline m fr of Fig. 2; andFig. 2, a plan View of the device as shown inFig. 1.

In the practice of my invention I provide a cylindrical cup orreceptacle 5, provided.

with a screw-threaded cap 5fL and in the bottom thereof with a vent 5b,and placed in the said cylindrical cup or receptacle is a ball 5C, thediameter of which is substantially the same as the inner diameter of thecup or receptacle 5, and said ball may be composed of metal or anydesired material of considerably greater specific gravity than oil. Thecup or receptacle 5 is provided at one side thereof near the removablecap 5qu with a tubular member 6, which communicates therewith at 7 andwhich ranges parallel with the cylindrical cup or receptacle 5, and `isprovided near the end thereof with an angular enlargement 8 and ascrew-threadedtubular eXtension 9 at the end thereof, within which is acylindrical bore 10, screw-threaded at its outer end, as shown Yat11,-andn provided at its inner-end with a conical valve-seat 12, and thebore 10 is in communication with the tubular member 6 by means of a portor passage 13. Within the bore 10 is placed an oil-dischargeregulatingplug 14, the outer end of which is enlarged and screw-threaded, as shownat 15, and the inner end of which is formed into a conical valve 16,which is split longitudinally, as shown at 17, and by screwing the plugtightly into the bore 10 the split conical valve or the separate partsthereof will be .forced together by the conical valve-seat, and

' formed in the hub' of the pulley or other device. The cap 5a is thenremoved and the receptacle 5 filled with oil, after which the cap isscrewed into position. As the pulley revolves, the specic gravity of theball being greater than that of the oil, the centrifugal forceoccasioned by the revolution of the pulley will throw the ball outtoward the cap 5L and force the oil through the tubular member 6, andsaid oil will pass through the port or passage 13 through the plug 14into the hub of the pulley or onto the shaft or axle on which the pulleyis placed, thus thoroughly lubricating said parts when the pulley is inoperation.

The vent 5b in the bottom of the cup or receptacle 5 is intended toprevent a vacuum in the inner end of said cup or receptacle in theoperation of the ball 5', as hereinbefore described.

My improved oiling device is simple in construction and operation andperfectly adapted to accomplish the result for which it is intended andmay be applied to any revoluble member mounted on a shaft or axle andprovided with a hub.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

An oiling device comprising a cylindrical cup or receptacle open at oneend and pro- IOO vided with a removable cap, a spherical ball or bodyplaced in said cup or receptacle a tubular member connected with oneside of` said cup or receptacle, near the cap end thereof and. rangingparallel with and slightly longer than said cup or receptacle, the freeend of said tubular member being provided with a valve-seat and a portor passage formed therein, and means for regulating the flow of oilthrough said port or passage, consisting of a split screw-threaded plughaving a coni ical end and a port or passage, substantially as shown anddescribed.

In testimony that I claim the foregoing as my invention I have signed myname, in pres- 15 ence of the subscribing Witnesses, this 9th day ofNovember, 1901.

ALBERT OBEN WYMAN.
